9.3.5 (Optional) Configuring LM for an LSP

This section describes how to configure single-ended or dual-ended packet loss measurement
(LM) to collect the reliability statistics of a bidirectional LSP.
Context
LM is an MPLS-TP performance monitoring (PM) function. Dual-ended LM is implemented
on two MEPs of an LSP. The measurement results are as follows:

l
The NE80E/40E supports two LM functions, namely, single-ended LM dual-ended LM. The
differences between them are listed in

Loss of ping packets
Run:
ping meg meg-name [ -c count-value | -t timeout-value | { mip ttl ttl-number
{ node-id node-id-value | mip-id mip-id } [ if-num if-number-value ] } ]
[ request-tlv ]
LB is enabled to monitor the connectivity of an MPLS-TP link.
NOTE
If the network speed is rather slow, timeout-value (a parameter specifies the period for waiting for a
response packet) can be set to a larger value when the ping meg command is configured.
Near-end packet loss: indicates the number and percentage of dropped packets that are sent
from an RMEP to a MEP.
Far-end packet loss: indicates the number and percentage of dropped packets that are sent
from a MEP to an RMEP.
Single-Ended LM
Statistics can be displayed by running either of
the following commands on the local MEP:
l Running the lost-measure single-ended
command can display on-demand
monitoring single-ended packet loss statistics
on the device.
l Running the display mpls-tp oam meg meg-
name statistic-type lost-measure single-
ended command can query single-ended
packet loss statistics.
